Very nice mine bending coloring exercise. Having done yesterday "Black Dots and the Four Pairs" from the same constructor helped a bit. It is those negative constraints that usually either get you or help you...

Excellent puzzle with very nice logic. Loved the way that the negative constraints worked. Thanks for setting!
